This paper deals with ASHRAE filters used in air filtration applications and summarizes, on the basis of current research work, some of the reasons for the disagreement that exists among filter manufacturers concerning the properties and performance of various types of air filter media in general, glass and synthetic media in particular. Attention is also drawn to some important items that need to be incorporated in test methods and to some factors that could be affecting filter performance

Antibacterial Efficiency

Use of an air filter material combined with antibacterial agents is one of the most effective methods to resolve the problem of air filter contaminated by pathogenic microbes. ε-Polylysine and Natamycin are two biogenic antimicrobials that have been widely applied in recent years because of their high antibacterial efficiency, harmlessness to human body and environmental friendliness. In this paper, a novel antibacterial air filter material was prepared by immobilizing ε-Polylysine and Natamycin onto fiberglass high efficiency air filter media by acrylate adhesive bonding. The mechanical properties, aerosol filtration properties, and antibacterial properties were then evaluated. An improvement in the mechanical properties of the material prepared was seen compared to the untreated filter media. The filtration efficiency of the material prepared for particle aerosols and bioaerosols both greater than 99.997%. Antibacterial efficiency of the material prepared against Staphylococcus aureus and Escherichia coli in suspensions were both greater than 99.99% compared to the untreated filter media. The anti-mildew effect against Aspergillus niger in suspension was strong compared to the untreated filter media. Antibacterial efficiency of the material prepared against bacteria in bioaerosols was greater than 99.99%. Observed with Scanning Electron Microscope, most bacteria on antibacterial filter media appeared to be dead. Thus, antibacterial air filter material prepared by immobilizing bio-antimicrobials on fiberglass had a strong inhibitory effect against gram-positive bacteria, gram-negative bacteria and fungi, with no impairment of the intrinsic properties. This kind of material appears to be promising for application in air cleaning and biological protection fields.

Recently, air quality is seriously worsening because of micro dust. As a result, respiratory and heart disease patients are also increasing every year. Therefore, the development of a highly efficient air filter media is required. In this study, we developed an antibacterial air filter media with activated carbon (AC) and cinnamon essential oil (CO). 12 wt.% polyurethane (PU) solution mixed with CO and AC was electrospun to prepare the AC+CO+PU nanofiber mat. We studied various characteristics of the AC+CO+PU nanofibrous mat. The surface morphology of mats in different concentration ratios was observed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). We confirmed the antimicrobial activity of the nanofibrous mat using zone of inhibition test with Staphylococcus aureus and Escherichia coli. Air filter test was carried out to observe air filtration efficiency and pressure drop. This data was used to calculate the quality factor of the fabricated nanofiber air filter media. The fabricated antimicrobial nanofiber air filter media can be applied to various fields such as personal masks, air purification devices and bio applications.
